Cometic 78-98 Volvo B23 97mm .051 inch MLS Head Gasket

This is a Cometic Multi-Layer Steel (MLS) head gasket designed for Volvo B23, B230, and B234 engines. It features a 97mm bore and a compressed thickness of .051 inches, making it a solid choice for rebuilding or replacing the head gasket on a wide range of Volvo models from the late 70s through the mid-90s, including popular cars like the Volvo 240, 740, and 940 series.

Cometic builds these gaskets with multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle high temperatures up to 482 degrees Fahrenheit and provides a reliable seal against the cylinder head and engine block. This construction means the gasket doesn't require any additional sealants, simplifying installation. MLS gaskets are well-suited for applications using aluminum heads with either aluminum or cast iron blocks, as they can manage the stresses between different metals.
